Cultivation Methods
Tragia adenanthera Baill. can be cultivated both indoors and outdoors. To grow it outdoors, plant it in well-drained soil under full sun. It can be propagated through seeds or stem cuttings, and the best time to do so is in the spring. Indoor cultivation requires bright, indirect light and a well-draining potting mix.
Watering Needs
Tragia adenanthera Baill. prefers evenly moist soil but can tolerate periods of drought. Water the plant when the soil feels dry to the touch but avoid overwatering as it can lead to root rot.
Fertilization
During the growing season, apply a balanced liquid fertilizer every two weeks to encourage healthy growth. Dilute the fertilizer to half its recommended strength to avoid burning the plant's roots.
Pruning
To keep Tragia adenanthera Baill. looking its best, it is recommended to prune it regularly. This helps to control its size and shape. Prune it in the spring before new growth has started. Use clean and sharp tools to make clean cuts, and remove any dead, diseased, or damaged leaves or branches.
Propagation of Tragia adenanthera Baill.
There are two commonly used methods to propagate Tragia adenanthera Baill. - by seed or stem cuttings.
Propagation by Seed
The seeds of Tragia adenanthera Baill. can be directly sown in the soil under the shade of a tree or a covered area. The seeds should be sown in the spring so that they get ample time to germinate before the winter. The soil should be kept moist, but not too wet, to promote germination. Germination can take from two weeks to two months. Once the seedlings grow a few leaves, they can be transplanted to their permanent location.
Propagation by Stem Cuttings
Stem cuttings can also be used to propagate Tragia adenanthera Baill. softwood cuttings taken in the spring and summer work best. Cuttings should be around 10-15 cm long and include at least three sets of leaves. Remove the lower leaves, dip the cut end in rooting hormone powder, and plant the cutting in a mixture of sand and moist peat. Cover the pot or tray with a plastic bag or plastic wrap and keep it in partial shade. Rooting should take around three to four weeks. Once roots have formed, pot the cuttings up individually into larger pots and keep them in partial shade until mature enough for transplanting.
